Definitions
- This invention relates to a method for manufacturing removable linings which are capable of snugly receiving tridimensional articles; a lining can considered to be, for example, a bed sheet, a protective lining for a mattress (under the sheet) or a lining for the upholstery of sofas and archairs and so forth.
- Methods are known, such as that illustrated by the U.S. Pat. No. 4,370,939 of 1/2/83 wherein, starting from a fabric roll, one obtains, at the outset, pieces having a preselected size.
- the corners of the pieces in question are cut away so as to provide four folds which are arranged one on each side and such that, by transversally sewing the confronting and adjoining edges a lining can be formed which has a substantially parallelepipedal configuration.
- peripherally sewn curls there are finally inserted, in registry with the four corners defined as aforesaid, resiliently stretchable members so as to make it possible to apply the lining stably while concurrently permitting the easy withdrawal of the lining.
- a parallelepipedal lining having a resilient angular zones for fastening of the kind referred to above originates a host of problems both from the point of view of the construction and upkeep and practical use.
- the sewing machine must be fitted with device for guiding the free edge, devices for detecting the transversal seams, devices for inserting the resilient member and for cutting it.
- Upkeep problems are originated by cloth-hanging pressing folding and storage, which are eminently felt in the industrial field, in which, for linings of the conventional outline these operations are made automatically by pressing and folding machinery.
- the principal objective of the present invention is to provide a method for making such removable linings so that one is enabled to start from a roll of fabric or nonwoven fabric and, by an entirely continuous run and in a cascade-like sequence of steps, a quite correctly folded lining can be obtained.
- An additional obejct is to provide an article which does not originate the motley crew of constructional use and upkeep problems referred to in the foregoing.
- a lining as obtained according to the method outlined above is characterized in that it comprises on extreme folds of at least one of two opposite sides, a folding of the edges sewn in the vicinity of the two nonfolded sides of the fabric piece.
- such a method also comprises the following steps:
- a lining of the kind described preferably has corrugation members on the extreme folds of at least one of two opposite sides, said members being slidable within sheaths provided by edging, said edging and said corrugation members being, in their turn, enclosed within the fold of said edges as sewn in the vicinity of the two nonfolded sides of the piece.
- FIG. 1 diagrammatically shows the stages through which the method according to this invention is carried out, in which, starting from a fabric roll, one obtains a finished lining which is quite correctly folded in plan.
- FIG. 2 shows a lining made according to this invention as finished and laid on a planar surface.
- FIGS. 3, 4 and 5 show the stages of placing such a lining onto a mattress
- FIG. 6 shows the same lining as before but differently applied to a mattress.
- a fabric wound on a roll is fed to a station 11 for application of a resilient member 12, which can be pulled out, for example, from two sideway dispensers 13.
- the stretchable member 12 is applied, longitudinally, in a preselected length, onto the fabric 10 and is sewn transversally at its two ends 14 by sewing and cutting machinery 15.
- the marginal edges of the fabric 10 are folded down onto the elastic band which has already been applied and a seamline 17 of the edges defines an edging 18 as a sliding sheath for the stretchable members 12 as such.
- a folding down 20 is caused to occur of the longitudinal edges of the piece, which are folded onto themselves widely enough so as to enclose also the edging 18 or the sliding sheath for the stretchable members 12, or of non-resilient cords for corrugating the fabric.
- Second sewing machinery 21 provide an angular sewing seam 22, which sets the fold 20 in position together with the stretchable member 12 at two spots 23.
- the fabric goes ahead its way and reaches another station 24, in registry with specially provided severing means 25.
- transversal sever 26 of the fabric 10 is carried out along a line passing through the apexes of two angular seamlines 22 placed confrontigly on two opposite sides of the fabric.
- a lining is provided, indicated generally at 27 and which, shifted laterally, is then brought to a station 28 whereas transversale sewing machinery 29 effects the finishing of the warp threads along the severing lines 26, so that the lining 27 is completed.
- the sequential order of the processing steps as described above by way of example only and without limitation can also be modified.
- the fabric immediately on completion of the application of the elastic band, the fabric can be severed and sent, after having been angularly shifted through 90°, to the subsequent folding and sewing stages.
- the application of the elastic band can also follow the severing operation and can be perpendicular to the direction of feed of the processing line.
- Devices for controlling and actuating the several processing stations are provided and such devices can be of any optical, mechanical and electronic type.
- photoelectric cells will be used, devices which count the stitches applied by the sewing machinery and devices which measure the fabric thickness as the fabric slides beneath appropriate feelers, so as to generate and to deliver to electronic counters the signal to energize or to deactivate the operative members which are present in the several stations.
- a lining 27 obtained in this way has, prior to being folded, the appearance shown in FIG. 2 and, more detailedly:
- the fabric piece 10 appears to be transversally cut along the lines 26 and is trimmed thereat and, perpendicularly to the lines 26 it has two end folds 20.
- seamlines 22 which are transversal to such angles and which latch, at 23, either end of the stretchable member 12, to the other end being stitched at 14.
- Each fold 20, having two seamlines 22, permits to define a seat 31 which is adapted to receive the ends of the articles to be wrapped, which, in the example shown in FIGS. 3, 4 and 5 is an end of a mattress 32.
- the figures show the several stages for positioning a lining 27 onto a mattress 32.
- FIG. 3 the lining 27 is placed above the mattress 32 with the folds 20 downwards.
- the end of the mattress is slipped into the seat 31 and once snugly fit therein, through a small opening 33 in the seam, the stretchable member 12 sliding with its central shank within the sheath 18 is pulled, so as to latch the lining 27 onto the mattress 32 (FIG. 5).
- angular folds 34 remain outside the lining 27 as best seen in FIG. 5, but it is possible to act for having an application of a different kind (not shown).
- the lining 27 in question could be placed above the mattress 32 but with the folds 20 pointing upward.
- the corners of the seatings 31 can be provided.
- the folds 20 are turned upside down so that the angular edges 34 are brought into the interior of the lining 27 and the latter lining 27, is slipped, turned upside down, onto the mattress 32 (FIG. 6).
- the angular folds 34 in an equivalent practical embodiment can be snipped away prior to finishing and folding the lining, by providing, additionally to the transversal severing means, 25, further cutting means (not shown in the drawings for the sake of simplicity).
- the ends of the stretchable members 12 pointing towards the interior of the fabric piece, instead of being sewn at 14 at the piece can be interlocked by a nonresilient member, for example a ribbon 35.
- a nonresilient member for example a ribbon 35.
- the article that is the lining, permits to simplify the upkeep especially when made with mechanical pressing and folding machinery, and storage of such linings is easy, in addition to the incontestable advantages of a great ease of application to and removal of the lining from the article concerned, a very satisfactory adaption also to different shapes being warranted, while concurrently providing a reliable fastening during use.
